Compate Z statistic and T statistic
Show transcribed image text Z statistic and T statistic Suppose you conduct a hypothesis test about a population mean when the standard deviation is known (a z test) by calculating a z statistic and determining whether to reject the null hypothesis. Assume that your z statistic is a positive value and that you will reject the null hypothesis when z is very large. For each of the potential changes to the components of your study design or the results listed as follows, determine the changes to the likelihood of rejecting the null hypothesis, and then select Increases, Decreases, or Stays the same from the dropdown menus in the right-hand column.
